Sudden freezes cannot find reason
I have bought recently Sapphire Radeon HD5450 1GB DDR3 PCI-E 2.1 graphic card.Put it in my motherboard,reinstalled Windows 7 Ultimate x64,and installed drivers for the graphic card.
From time to time,my computer suddenly freezes.At the "freezed" period (which I suppose can last as long as I let it,because I have tried,and nothing special happens),music stops playing,mouse cursor freezes,unable to CTRL+ALT+DEL to see whats happening.Also,the CPU led at that time is working "on a low level",i.e.constant red light,but not as intense as when system is performing some task.
The only thing I can do,in order to boot successifully,is to turn off machine,unplug it,remove motherboard battery for a few minutes,than put it back,plug in power,and turn it back on.The only changes I make in BIOS afterwards are to disable onboard audio since I have sound card,and set up Smart Q fan monitor for CPU,to lower the noise.
There is nothing in Event Viewer,no crash dump or minidump file to analyze.I just dont know where to start from.
I hope someone has any idea where to start from.
